Wave Basics
What type of wave has particles that move perpendicular to the direction the wave travels?
Transverse wave
What measurement describes the distance from the resting position to a crest or trough?
amplitude
What is the number of complete waves that pass a point in one second called?
frequency
What is the distance between two corresponding points on consecutive waves called?
wavelength
What type of waves can travel through empty space without a medium?
electromagnetic Waves
What is the highest point of a transverse wave called?
crest
What does a wave with a greater amplitude carry compared with a wave with a smaller amplitude in the same medium?
more energy
What unit is used to measure frequency?
Hertz
How is one wavelength measured?
trough to trough or crest to crest
What is the name of the complete range of electromagnetic waves arranged by frequency and wavelength?
What is the electromagnetic spectrum?
What is the lowest point of a transverse wave called?
trough
If the height of a wave increases, what happens to its amplitude?
it increases
If 10 complete waves pass a point in one second, what is the frequency?
10 HZ
If the distance between crests decreases, what happens to wavelength?
it decreases
Which electromagnetic waves have the longest wavelengths and lowest frequencies?
Radio Waves
What is the distance from one crest to the next crest called?
wavelength
Which wave has greater amplitude: a wave with a height of 2 cm or one with a height of 6 cm?
one with a height of 6 cm
If frequency increases while wave speed remains constant, what happens to wavelength?
It decreases
Two waves travel at the same speed. Wave A has a longer wavelength than Wave B. Which wave has the lower frequency?
The one with the longer wavelength
Which electromagnetic waves have the shortest wavelengths and highest frequencies?
Gamma Rays
What type of wave transfers energy without transferring matter overall?
Transverse Wave
If the height of a wave is 12 cm, what is its amplitude?
6 cm
As frequency increases, what other property increases with it?
Amplitude
A transverse wave has a wavelength of 4 meters and a frequency of 3 Hz. What is its speed?
12 m/s
